Escort mk7 ECU swap - escort99
hi,
me and a friend have recently swapped the engine in my 1999t escort from a 1.6 zetec (snapped cambelt, uneconomical repair) to a 1993k 1.8 zetec 105ps (free donor car that ran perfectly) the car runs rough with the original ecu (assumed mapping/lean mixture etc).
the problem we've encountered is that due to the 1.6 ford immobiliser we don't seem to be able to start the car using the original 1.8 ecu, so the question is : when buying a second hand 1996 onwards immobiliser-compatible ecu (ebay seems to have some) will it need to come with any ther kit for the immobiliser (compatible transponder key etc) or can it just be plugged straight in and started. i've searched the web but got no straight answers.

please help as everything went well up to this point.

every escort ive worked on has the pats box for the immobiliser up the dash and it is seperate from the ecu,therefore i personally am happy to say its not an immobiliser problem more a fuse box compatability problem or a loom to ecu (pins out) problem

sorry mate

by all means i am happy to be proved wrong though

thanks for the tip, but i'm still not 100% sure whether to
go ahead and get the ecu or not.
i've been doing more research and came across some
part number info

ECU codes:-

105.......92/93......92FB12A650CD (short code 2FCD)
105.......92/93......92FB12A650CE (short code 2FCE)
105.......94 on......94FB12A650BB (short code 4FBB)

130.......92/93......92FB12A650BC (short code 2FBC)
130.......92/93......92FB12A650BD (short code 2FBD)
130.......93/94......92FB12A650BE (short code 2FBE)

i'm thinking try to get a 4FBB ecu, any comments ?
any more tips ?

sorry for delay in reply, been on holiday.
